There seem to be a lot of loose ends and questions left.
First is the obvious - we KNOW Sol and the jedi with him did something the night of the fire. He's repeatedly said he'll "explain everything" and he feels guilty about something. THIS was the central question for the first 3 episodes, but it was kind of forgotten during the last two. Seeing the jedi as less than perfect fits nicely with the stories we have going on now here. That they are blinded to their own internal problems helps explains what they don't know and their eventual downfall generations later. But the story-telling ...
Second, we learned in the first episode that there is an effort to curb use of the force outside of the jedi order. That seemed to be what Qimir was referring to. I actually hated the line that the jedi would call him a sith. SITH hasn't been defined, the word dark side hasn't been used. Whether he is actually a sith or not, it was a stupid line. It doesn't bother me that much that there might be a "sith" around now - I don't think it hurts the all sacred canon (everyone on this forum used or uses Legends material, which has been declared non-canon anyways).
Here's a few lines I think would have been better:
"I'm what the jedi fear - someone not under their control"
Or more fleshed out:
"I'm like you. I have the force at my side. But unlike you, and your jedi, I see the full power of the Force. Generations ago, my people were cast out by the jedi centuries ago for daring to have ambition, for daring to use their power. Your history books would call them sith, wielders of the dark side of the force. And their knowledge has been passed down, generation to generation, master to apprentice (((or master to acolyte)), until me. You think I am the bad guy, but your self-righteousness is undeserved. You and your jedi are just as ambitious, just as power hungry, as me. I just don't pretend, like you do"
It's stil rubbing me the wrong way, the pacing, the dialogue. I feel like there is a good story here, but they are either rushing to tell it, or just assume certain knowledge, or don't care what we don't know. Even if there was a "big reveal" at the end, I don't think it will necessarily be earned.
